Here's what's new, fixed, and broken in Windows 10 Build 14936

Microsoft today released a new build of Windows 10 to Insiders in the Fast Ring for PCs and Mobile devices. The latest build, 14936 brings a number of bug fixes and improvements — however, there aren’t any new features which isn’t really that disappointing. Build 14936 fixes a bug which caused Explorer to crash for some users, and it also fixes a bug which prevented Microsoft from releasing build 14931 for Mobile devices last week.

Here’s what’s new, fixed and broken in this:

WHAT’S NEW

What’s new

Authentication changes affecting connectivity to NAS devices and home file servers

After updating to the latest Insider Preview builds, you may have noticed that shared devices on your home network have disappeared from your home network folder. You may have also noticed your mapped network drives are not available. If you change your network to “private” or “enterprise”, it should start working again. For more information on this behavior change, see this Microsoft Security Bulletin.

Windows Subsystem for Linux (WSL) Updates

WSL will install Ubuntu version 16.04 (Xenial) instead of Ubuntu 14.04 (Trusty) in an upcoming release. This change will apply to Insiders installing new instances (lxrun.exe /install or first run of bash.exe). Existing instances with Trusty will not be upgraded automatically. Users can upgrade their Trusty image to Xenial using the do-release-upgrade command. Full WSL release notes can be found here.

WHAT’S FIXED

What’s fixed

For PCs:

• We fixed the issue causing Narrator to continually speak the progress of a song e.g. update with the current time of the progress bar every second if you navigate to the progress bar while a song is playing in Groove Music.
• We fixed the issue where using the tab key to navigate the Settings app wouldn’t work.
• We fixed an issue resulting in Explorer.exe frequently crashing for some Insiders, particularly for those with multiple network switches.

For Mobile:

• We fixed the issue causing the pin pad to not be visible to unlock the phone even after rebooting the phone.
• We fixed the issue where some phones lose the ability to use their SIM cards.
• We fixed the mobile hotspot issue where it works the first time but subsequent attempts to use the feature won’t work until the phone is rebooted.
• We fixed an issue causing some devices such as the Lumia 650 from failing to install a new build with Error 0x80188308.
• We fixed the issue causing some build updates to fail with an 800703ed error code.
• We fixed the issue where Action Center no longer closes if you swipe up on the empty space (area of Action Center that doesn’t show any notifications).
• We fixed an issue where notifications were unexpectedly showing the app logo within the notification when viewed in Action Center.
• We fixed an issue for devices that shipped with Windows Phone 8.1, such as the Lumia 930 and 1520, where if you plugged in a headset during an ongoing call, the audio would not be routed to the headset.

WHAT’S BROKEN

What’s broken

For PCs:

• Optional components may not work after upgrading to this build. To get it working again, go to “Turn Windows features on or off”, scroll down and check the right optional component and click ok.  After a reboot, the optional component will be enabled again.
• Tencent apps and games will cause your PC to bugcheck (bluescreen).
• Running sfc /scannow in an elevated command prompt will fail at 20% with the error “could not perform the requested operation.”

For Mobile:

If you have your default storage set to a SD card for apps, installation of apps like WhatsApp, Facebook Messenger and WeChat will fail with an error. As a workaround, set your default location to your device’s onboard storage.
